Polish prosecutors said Tuesday they will not "anytime soon" establish the causes of the plane crash that killed president Lech Kaczynski and dozens of high-ranking officials in Russia on April 10, dpa reported. Russian investigators were "kind and willing to work together" with the Poles, who were leading a separate investigation into the crash, said Andrzej Seremet, Poland's chief prosecutor. Poland has asked Russia for "all significant evidence" secured by the Russian side, Seremet added. All theories as to what cause the Russian-made Illuyshin plane to crash were being considered equally, the prosecutors said at a press conference in Warsaw. Investigators would in several days complete their analysis of a third black box, which registered the data of the flight that crashed in Smolensk, Russia, they said. Some 21 bodies had still not been identified and required DNA testing, the prosecutors said. -- SPA
